I use a php form to allow users to register to attend events. The form surveys for basic information.
The problem is people who have already attended events are having to answer the same questions.
I want to put another form in front of this that will have an initial step asking for email address.
Once submitted the new script will check MySQL to see which fields are empty for that person and the next page of form will only present fields needing to be populated.
I will manually upload this info to MySQL.
On submit of second page all data will be posted to the form fields currently in use by hidden fields.
